(TNS) — Homeowners checking on their investment, prospective buyers researching values and curious lookie-loos lost access to the Maryland Department of Assessments and Taxation’s real property database website on April 14, when administrators noticed suspicious activity and took the site offline.

“The official Maryland Real Property Search site is undergoing emergency maintenance. We apologize for the inconvenience,” greets those who try look up addresses on the website, as well as directions to make requests about specific properties and a warning: “Maryland residents and businesses should only use the official SDAT Real Property search page. … Users should avoid any third-party websites or unofficial links claiming to provide SDAT property records, as these may not be secure.”

The outage is ongoing as the state’s investigation continues, department spokesperson Alyssa Nolte told The Baltimore Sun in an email.

“On April 14, 2026, the Maryland Department of Information Technology detected suspicious activity on servers running the State Department of Assessments and Taxation’s Real Property Search website application,” Nolte wrote. “In response, DoIT quickly took the website offline to contain potential threats and conduct an investigation of the suspicious activity.”

So far, the investigators believe that no private, personally identifiable information was compromised, she said, as the servers contained only publicly available information. The database will remain offline until the investigation concludes that the system is secure.

Although the main customer of the real property database is homeowners, she said many real estate industry professionals, other businesses and nonprofits use its information. Real estate workers, inspectors and other industry specialists use the database, but also have access to other proprietary data libraries.

The Maryland Real Estate Commission has not heard any complaints from licensed agents, a representative told The Sun.

Maryland officials do not anticipate a broader cybersecurity risk to the state at this time, although their internal investigations are ongoing.
